The trapezoid above has a base of 38 m and a height of 12 m.

Which set of dimensions would produce a similar figure?

A. base = 114 m, height = 36 m
B. base = 38 m, height = 36 m
C. base = 119 m, height = 36 m
D. base = 109 m, height = 36 m

1. well, the new base:height ratio would have to be the same: 38/12 = 19/6

So, since all the choices have h=36, which is 6*6, we need a base of 6*19 = 114

Looks like A to me.
